I sometimes wonder about the efficacy of some of the stuff the advertisers tease us with and what they are made of. How many are snake oil in a can.
At present in the UK motoring press Wynns are making a thing about their blocked DPF cleaner...
WYNNS DPF REGENERATOR - 500ML 981AA1390A quick googling has produced lots of mixed comments on car forums - some swear it did the job - others claim it didn't. I find it hard to see how it works after being thoroughly burned during the cylinder firing stroke.
3 years ago I bought some wheel cleaner and recognised its smell. We had recently moved house and I had bought 5 litres of brick cleaner to get mortar stains from some walls. Bugger me - when I looked at the ingredients for the brick cleaner and wheel cleaner they were virtually the same (hydrochloric and phosphoric acids in low concentrations). The main difference was that brick cleaner was a tenth of the price.
One of my friends is a strong believer in diesel additives to improve engine power in his Astra. He used to use a proprietary additive but then "discovered" it was two stroke oil by another name. So he now buys 2 stroke oil at a quarter of the cost. I don't use either.
The car cleaner and car polish industry must be heaven for smart marketing managers who recognise our gullibility a mile off.
One of my grandsons has fitted his diesel polo with an exhaust a lorry would be proud of and has fitted a second hand chip tuning box. He swears that the car is now "heaps more powerful and uses far less diesel". Some hopes says I.
What other stuff do we fall victim to I wonder......
